Application led May 28, 1915. Serial No. 30,955.

To all whom it may concern Be it known that I, JAMES J. COOPER, a citizen of the United States, residing at the f city of St. Louis, State of Missouri, have invented a certain new andiuseful Improvement in End Construction for Box-Cars, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part v of this specification.

This invention relates to certain improvements in sheet metal ends for box cars.

The object of the invention is to provide an improved form of end made up of corrugated sections of sheet metal, and containing features designed to provide an exceptionally secure attachment to the car superstructure.

A further' object of the invention is the provision of an improved arrangement for securing car ends to the car superstructure.

Otherobjects of the invention will be obvious or pointed out hereinafter.` f

In the accompanying drawings, which illustrate one embodiment of the invention, Figure 1 shows a front elevation of one of the car ends; Fig. 2, a vertical section on line 2-2 of Fig. y1; Fig. 3, a horizontal sectionon line 3?-3 of Fig. 1; Fig. 4, a detail taken at the corner of the car; Fig. 5, a detail showing a front view of a modified feature; Fig. 6, a detail illustrating a vertical section substantially on line 6-6 of Fig. 5. Fig. 7 is a partial elevation illustrating a modified form.

In the embodiment illustrated in these drawings, it will be seen that I provide an end formed of three sections, `1, 2, and 3, although it is obvious that any desired number of sections may be used to form the end wall. In this form, the sections are connected on horizontal lines, the lower edges of the upper sections being overlapped on the exterior of the upper edges of the subja- In each of the sections is an outwardly pressed corrugation 5 extending longitudinally of the section, preferably highest at the median line of the section and gradually tapering back into the plane of the body portion ofthe section as it approaches the margins. At the ends of these pressed out to form inwardly opening pockets 6 having the walls 6a toward the margins of the sections lying at substantially right angles to the body plane of the sections, and the walls opposite thereto merging gradually back into the plane of the sections. The margins of the sections are flanged rearwardly from the body plane thereof to pro-vide the attaching flanges 7.

When the end is applied to the ear superstructure, themarginal flanges 7 are placed to embraceI the corner posts 8 and, anchor plates 9 are aiiixed to the inner w`alls of the car with ends projecting beyond the`corner posts, said plates extending rearwardly from the end of the car as far as desired and being bolted to the transom posts or ,other framing members of the car superstructure. TheA projecting ends of the anchor plates vare adapted to project within the pockets 'operate with the corrugations 5 to form beams extending longitudinally of the sections, said beams being securely axed to the car superstructure at their ends by the anchor plates 9. Anchor pla-tes ll similar to anchor plates 9, may be applied to the exterior car walls and bolted through ianges 7 and the walls and frame members to the anchor plates 9, as illustrated in Fig. 3. l In Figs. 5 and 6, I have illustrated a modified arrangement in which the walls 6h of the pockets 6 taper obliquely back into the plane of the sections. A diagonally dlsposed anchor plate l2 may have its end secured 1n a pocket of this conformation, said anchor plate extending back obliquely to one of the upper or lower longitudinal framing members of the car superstructure. This construction provides an exceptionally sturdy end by virtue of the stiffness imparted by the beams extending longitudinally of the sections, and theisecure attachment of the secwhen said sections are joined. This oifset is oi' substantially the same cross sectional form as that illustrated in Figs. 3 and 4, and tapers back into the plane` of the upper and lower sections. l(This oifset portion in addition to affording, a securing place for theanchor I -strips 9 in the fashion illustrated in Figs. 3

. pockets.

and 4, or the strips 12, as illustrated in Figs. 5 and 6, provides in eiect an auxiliary corner post, acting as a continuous-strengthening member from top to bottom of the end structure, operating to stillen the end and act as a load-carrying member adjacent the Acorners of the car.

4 `I am aware that the device is capable of various modiications and changes not herein specically illustrated and described,without departing from the spirit and scope of the invention. 1 y

What I claim is:`

1. In a car structure, an end sheet extending transversely between the side walls and having outwardly pressed pockets formed therein adjacent its lateral extremities, and

`anchor plates secured to the sides of the car and having their outer ends secured in said 2. In a car frame members, an end sheet extending between said frame members and having portions adapted for attachment thereto, said sheet having integrally formed pockets adjacent the frame members and removed from its edges, and anchor plates secured to frame members and within said pockets on the interior of the car.

3. Ina car, an end sheet extending transversely between the Vside walls and adapted for attachment to the corner posts, said sheet having a portion apart from the margin thereof disposed transversely of the major plane of the sheet," and securing means attachedto a side wall portion and to said transversely directed portion ofthe sheet.

4. In a car, an end sheet extending transversely of the car and having a marginal flange directed substantialy at right angles to the majorplane of the sheet, said sheet having a transverselydirectedportion extending substantially at right\'angle s from the major plane of the sheet and spaced apart from said marginal flange, and attaching members secured to the car wall and to said marginal flange and said transversely directed portion. 's l.

V5. In a car, a sheet forming a wall portion of the car, said sheet being shaped to provide a pocket spaced apart from itsmargin, said pocket havin a wall extending at an angle from the ma] or plane of the sheet, and an anchor member secured to said pocket wall and .to a portion of the car body.

6. In a car, an end sheet having its lateral margins attached to car wall portions, said sheet being provided with a horizontally disposed corrugation, said sheet having defiected portions at the extremities of said corrugation extending at an angle from the major plane of the sheet, said deflected portions being spaced apart from the' lateral margins of the sheet, means for securing the lateral marginal portions of the sheet to wall portions of the car, anchor members secured to said deflected portions and to car wall portions, and a tie plate covering the ren-- trant side of said 'corrugation and alixed t0 the end sheet at the sides of said corrugation, said tie plate being aflixed at its extremities to the anchor members.

7. In a car, an end sheet having its lateral margins attached to side wall portions, anchor memberssecured to side wall portions and aixed to saidI sheet at .points spaced apart inwardly from said margins, and a tie strip having its extremities connected to said anchor members and connected to said end sheet intermediate its extremities.

8. In a car, a wall sheet having attaching pockets with lateral walls formed adjacent opposite margins, a stifening corrugation formed as a continuation of said attaching pockets, and attaching members seated in said pockets and secured to the lateral walls thereof.

9. In a car end, a wall sheet formed with attaching pocketsv adjacent opposite margins and with a stifening corrugation extending intermediate said pockets, 'and a plate aflxed to the inner side of said wall sheet and covering the rentrant sides lof said pockets. and said corrugation.

10. In a car end, a wall sheet formed with attaching'pockets adjacent opposite margins and with a stiffening corrugation extending intermediate said pockets, attaching members affixed to said wall sheet in said pockets, and a plate affixed at its extremities to said attaching members and intermediate its extremities to said wall sheet in 4position to cover the rentrant sides of said corrugation and said pockets.

11. A car end composed of a plurality of sections horizontally disposed and secured together along their meeting margins, the lateral portions of said sections being secured to car wall portions, and anchor members secured to longitudinally deflected portions of the respective sections at points inset from their lateral margins and in position for attachment to car wall portions.

12. In a car, an end sheet extending belll tween the corner posts and having portions ehor member being secured to the en'd sheet adapted for attachment thereto, and anchor insiderthereof at a point beyond the plane of members secured to side portions of the car the end Wall.
